  • Patent number: 7332536
    Abstract: Compounds and compositions comprising specific metal salts of hexahydrophthalic acid (HHPA) in order to provide highly desirable properties within thermoplastic articles are provided. The inventive HHPA derivatives are useful as nucleating and/or clarifying agents for such thermoplastics, are practical and easy to handle. Such compounds provide excellent crystallization temperatures, stiffness, and acid scavenger compatibility within target polyolefins. Also, such compounds exhibit very low hygroscopicity and therefore excellent shelf stability as powdered or granular formulations. Thermoplastic additive compositions and methods of producing polymers with such compounds are also contemplated within this invention.
    Type: Grant

    Date of Patent: February 19, 2008
    Assignee: Milliken & Company

  • Patent number: 5973064
    Abstract: This invention relates to colored polyester thermoplastics comprised of polymeric colorants having poly(oxyalkylene) moieties and/or anionic dye/quatenary ammonium substantially inorganic salt-free colorant complexes mixed with diluents selected from the group consisting essentially of sorbitan (C.sub.8 -C.sub.22) monoesters, ethoxylated sorbitan (C.sub.8 -C.sub.22) monoesters, mixtures thereof of sorbitan (C.sub.8 -C.sub.22) monoesters and ethoxylated sorbitan (C.sub.8 -C.sub.22) monoesters, ethoxylated nonyl-phenol ethers, ethoxylated dodecylphenol ethers, mixtures thereof of said ethoxylated nonyl-phenol ethers and ethoxylated dodecylphenol ethers, and mixtures of (i) sorbitan (C.sub.8 -C.sub.22) monoesters or ethoxylated sorbitan (C.sub.8 -C.sub.22) monoesters and (ii) ethoxylated nonyl-phenol ethers or ethoxylated dodecylphenol ethers.
